Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531396, here are decompositions:

13 + 531383 = 531396
37 + 531359 = 531396
43 + 531353 = 531396
53 + 531343 = 531396
59 + 531337 = 531396
97 + 531299 = 531396
109 + 531287 = 531396
157 + 531239 = 531396

Showing the first eight; more decompositions exist.
